The streamline is a basic position for competitive swimming starts mid turns and has been used in many studies on resistive forces. However, there is a wide yahweh, of theoretical interpretations in these studies, leading to diverse and questionable conclusions. The purpose of this study was to determine performance level differences in the streamline position using a meta-analysis. Faster swimmers had a significantly lower coefficient of drag ([C.sub.d]) than slower, swimmers, (M = .57, z = 4.30, p [is less than] .001, SE = .13, 95 % CI =.32-.82) and, therefore, a more effective streamline position. The results support considering all the related variables in a study of passive drag and using the [C.sub.d] to discriminate between performance levels in swimming.
